LEWIS W. HAS SELMAN, OF INDIANAPOLIS, INDIANA.

PORTABLE ENGINE.

SPECIFICATION forming part of Letters Patent No. 224,427, dated February10, 1880. Am cation filed November 20, 1879.

To'all whom it may concern Be it known that I, Lnwrs W. HASSELMAN, ofthe city of Indianapolis, county of Marion, and State of Indiana, haveinvented certain new and useful Improvements in Wheel Attachnients forPortable Engines, of which the following is a specification.

Reference is bad to the accompanying drawings, which are made parthereof, and on which similar letters of reference indicate similarparts.

Figure 1 is a side elevation of a portable engine having my improvedattachment. Fig. 2 is adetailed section, on an enlarged scale, showingthe attachment more clearly.

In said drawings the portion marked A represents the boiler of anordinary portable engine; B, the hind carrier-wheels; G, the frontcarrierrwhecls; D, the front axle-tree; E, a horn-like projection, whichconnects the boiler to the axle-tree. and which is the attachment thatforms the principal element of myinvention F, the main drivingbeltpulley; G, the shaft to said pulley; and H, lugs attached to the frontend of the boiler, which form the bearings for said shaft.

The object of my said invention is to provide ameans which will admit ofthe drivewheel being lowered, so that its lower side will beconsiderably below the upper side of the carrier-wheel nearest it, andat the same time allow the latter to circle freely about the former.This I accomplish by running the shaft for the drive-wheel across thefront end of the boiler and making the position of the king-boltvertically underneath said shaft, or nearly so, by means of aforwardly-projecting attachment fastened to the bottom of the boiler.

Heretofore the attachment employed in this connection has projectedvertically downward from the bottom of the boiler rather than forwardly,as does mine. With such an attachment, while the drive-Wheel couldoccupy the same position shown in my drawings, the carrier-wheels couldnot turn to he extent to which they should without striking it. Toobviate this disadvantage some engines have been made with thedrive-wheel shaft placed over the top of the boiler; but as such alocation makes it necessary to also raise the steamchest and cylinder,thus making the engine top-heavy, it has made that steadiness of motionwhich all engines should have difficult to obtain, and made them moreliable to topple over when passing over uneven ground. Such anattachment of the shaft and cylinder is more likely to wrench or strainthe boiler and cause it to leak than when they are attached to the sidesand lower down.

As hereinbefore indicated, I am aware that engines have been constructedwith the drivewheel shaft vertically above the front axle, and probablymore engines are constructed with the peripheries of the drivewheel andcarrier-wheel passing each other than in any other way, as it is verydesirable that they should. I have, however, never seen the formerfeature combined with the latter, which it must be, in order to comewithin the scope of my invention or to accomplish its object.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination of the wheel F, mounted on a shaft, G, running infront of the boiler A, and mounted upon bearings attached to the sidesthereof, with the wheel 0, mounted upon the axle D, which is pivoted tothe forwardlyprojecting attachment E upon the under side of the boilerwhen the pivot-point of the axle D is vertically beneath the shaft G andthe peripheries of the wheels F and 0 pass each other, all substantiallyas shown and described, and for the purpose specified.

2. The combination of the wheel F, shaft Gr, wheel 0, and axle D, theshaft G being attached to bearings attached to the sides of the boilerat a point below its top, and the axle D being pivoted at a pointvertically below said shaft, while the peripheries of the wheels passeach other, all substantially as and for the purpose specified.

In witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 10th day of November, A. D. 1879.
